Case Type   : gs_checkse工具功能
Case Name   : 验证gs_checkse的A1检测项确保数据库实例的最大连接数配置正确检测与修复成功
Create At   : 2024/10/23
Owner       : lihongji
Description :
    1.设置max_connections为17后检测A1项
    2.修复A1不符合安全规范项目后再次检测
    3.设置max_connections为26000后检测A1项目
    4.修复A1不符合安全规范项目后再次检测
    5.通过gsql登入数据库查看max_connections参数值
Expect      :
    1.打印max_connections参数的告警信息
    2.修复成功、再次检测不打印max_connections参数的告警信息
    3.设置max_connections为26000成功，打印max_connections参数的告警信息
    4.修复成功、再次检测不打印max_connections参数的告警信息
    5.max_connections参数值为5000
